FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Sept. 22, 1914.

Application led September 7, 1911-. Serial No. 648,007.

To all wkom tmay concern Be it known that I, FRANK M. ASHLEY, a citizen? of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improveniente in Fountain-Pens, of which the following is a specification.

My' invention relates to fountain pens and one object of my invention is to provide a fountain pen having a valve located near its front end by means of which the passage through which ink iiows from the reservoir to the pen may be closed in a. simple and eiiicient manner.

A further object is to provide a construction in combinationr with said val-ve by means of which the reservoir may be filled with ink.

-A further obje-ct is to provide a fountain pen in which there are no joints in thecasing which come in contact with the fingers when the penis held as in the act of writing, and soil the fingers of the writer in case the reservoir should leak at said joint.

- A further object is to provide ay valve construction which will not easily stick and hecome inoperative by reason of the ink drying between the movable parts of the valve.

A further object is to provide a fountain pen in which there are no threaded joints at ther forward end thereof.

Referring to the drawings, Figure 1 is a longitudinal sectional view of a fountain penv embodying one form of my improved valve construction; Fig. 2 is a similar view embodying a slightly modifiedl form of valve, and also the' self-fillingdfvices in combination therewith. Fig. 3 isA a' similar view and construction to that shown inl Fig. 2, except that the pen section does not abut an inner' shoulder formed integral with the casing.

Referring to- Fig. 1, indicates acasing having a reservoir 1-1 closedy at its rear end by a cap lwhich is fastened to the casingby screw threads. The casing l0 is provided with a cylindrical bore 13 which extends rear endthereof for a short distance to a shoulder 14 at which point a 'smaller cylindrical bore 15'communicates with the reservoir 11. Fitted to slide snugly in the bore 15, is a plug 16 pro-videdv with an ink-duct 157 of the same w dei ma depth es ne insduct 18y formed thel feed-plug 21, which ink-duct is of the usual form and dimensions commonly used in fountain pens.

The cylinder 19 may have a smooth outer surface as illustrated or may have its outer surface formedas illustrated in Fig. 2', and is fitted to closely fit the inner surface of the bore 13 to slidingly engage said surface, and is of a thickness-corresponding to the height of the shoulder 14,- and abuts said shoulder as illustrated, and is provided at its front end` with an annular flange 2() whichl preferably abuts the end of the casing 10 and is of sufficient width to be grasped between the thumb andy fore-linger to turn the cylinder in the bore 13.

The feed-plug. 21' fits closely in the cylinder 19 and' is of the' same diameter as the plug 16 and abuts said plug so that ink may flow from the reservoir 11 through the inkducts 17 and- 18 to the pen 22 when said inkducts are in alin'ement with each other. By rotating the cylinder relative tothe casing the ink-ductsI are thrown out of alinement and .the valve, comprising the plug 16, cylinder 19l and feed-plug 21, closed. To provide for ad'j-ustment'of the pen 22, the feedplug may be moved longitudinally in either direction relative to the casing and the plug 16 moved to correspond andI abut the feedplug to forml the valve, as wil-l be easily unvthis construction from that of Fig. 1 is, that instead of the front end of the cylinder 19 tern' inatingv in a flange like that indicated by 20 in Fig. 1, itis provided with a taperingl end as illustrated and indicated by 23. Fig. 2 also contains the self-filling construction comprising a small tube 24 which is connected to. and' extends through the plug 16, its forward end being shown as closed by the rear end of the feed-plug 21- when the inkducts 17 a'nd 18 are in alinement, and its opposite' end located near the rear end of the reservoir. The inner diameter of the reservoir. is reduced to provide a bore 25 in which is held one end* of a soft rubber sack 26 by in'ewns of a' hard rubber nipple 27 the outer surface' of which is formed cone-shaped' and of proper diameter toI be inserted inthe sack andl cla-mp the' sack against the casing. A cap'28 covers the sack and is threaded tothe endI of the casing at 29.

The cylinder' 19' is provided with a plurality 1 of ooi'centric"` grooves 30-30, etc., placedclose to .ether to provide bearing surfaces of limite area in contact with the sui'- face of the bore 13- to'reducethe friction and danger of sticking in case ink gets'in the joint lubricating material such as graphiite or .stiifgrease may be inserted in these grooves which 'thus further reduces the'friction and electually-prevents the lealn'ngof the ink past the joint, particularl inasmuch as thel writing. iiuid'and'llthe lubricating ma terialdo not mix. 1 z 4i The constructionillustratedin Fig. 3'i's the same as that illustrated in Fig. 2, except that :the plug 16 is of the saine diameter as the bore `13 andthe shoulder 14 is dispensed with. Y l

-In allof the forms I have disclosed, there is only one joint atthe bottom end of the barrel, whichjoint is located close to theend of the barrel `so as to' avoid -the possibility of soiling the fingers.4 The cylinder is elongated suiiiciently` to obtain a' long contacting surface engaging with the bore and thus the possibility 'of leaking at the joint -is obviated.

The operation of illingthe reservoir ywith ink is as follows: First rotate the cylinder the ink-duct 19 is in 'alinement with. thetube 24, then remove the cap'28 and place the front end ofthe cylinder beneath the surface of the ink andv then collapse the sack 26 by pressing between the thumb fore-linger to expel a volume of air equal to ithe ca acity of lthe sack, `through the tube and in ducts to the atmosphere, then allow the sack to expand, thereby drawing ink through the ink-ducts and tube and into they reservoir where it is trapped. By repeating this operationfa few times the reservoir 'is illedand when'full the ink can be felt 'in the sack or pump. By turning the cylinder a i turn the reservoir is closed and no ink caniescape therefrom. By turning the cylinder turn from its lling position,'the ducts arev brought in alinement. and the pen may then be used for writing.

Having thus described my invention, I claimasnew l1. 'A 'fountain penv comprising a casing having a reservoir formed therein and provided with a-bore atits vforward end yand having 'a partition between said bore and the reservoir provided withan ink-duct, a cylinder fitted to rotate in said bore, and a longitudinally movable feed-plug fitted snugly in said cylinder and extending therethrough, the rear end of said plug closely abutting said partition and having an ink-duct formed in one side thereof adapted to register with ther ink-duct in said partition in one po- .sition of rotary adjustment, and to be out of registry with the ink duct in the partition in another position of rotary adjustment, the
